Article Introduction：Key Points GD and ImageMagick are both popular PHP image processing libraries. GD is more widely used and ImageMagick is more powerful. In terms of performance, there is no absolute advantage or disadvantage between the two, and the speed depends on the specific application scenario. The encoding styles are significant. GD adopts procedural programming, and ImageMagick supports object-oriented programming through the Imagick class. In addition to these two libraries, there are other options, such as cloud image processing platforms or components that have been integrated into the application. introduction In PHP applications, if you need to create thumbnails, apply image filters, or perform other image conversions, you need to use the image processing library. Usually, you'll choose GD or ImageMagick. But which library

Article Introduction：Using ID selectors is not inherently bad in CSS, but should be used with caution. 1) ID selector is suitable for unique elements or JavaScript hooks. 2) For general styles, class selectors should be used as they are more flexible and maintainable. By balancing the use of ID and class, a more robust and efficient CSS architecture can be implemented.

Article Introduction：Create custom middleware in ASP.NETCore, which can be implemented by writing classes and registering. 1. Create a class containing the InvokeAsync method, handle HttpContext and RequestDelegatenext; 2. Register with UseMiddleware in Program.cs. Middleware is suitable for general operations such as logging, performance monitoring, exception handling, etc. Unlike MVC filters, it acts on the entire application and does not rely on the controller. Rational use of middleware can improve structural flexibility, but should avoid affecting performance.

Article Introduction：Polymorphism is a core concept in Python object-oriented programming, referring to "one interface, multiple implementations", allowing for unified processing of different types of objects. 1. Polymorphism is implemented through method rewriting. Subclasses can redefine parent class methods. For example, the spoke() method of Animal class has different implementations in Dog and Cat subclasses. 2. The practical uses of polymorphism include simplifying the code structure and enhancing scalability, such as calling the draw() method uniformly in the graphical drawing program, or handling the common behavior of different characters in game development. 3. Python implementation polymorphism needs to satisfy: the parent class defines a method, and the child class overrides the method, but does not require inheritance of the same parent class. As long as the object implements the same method, this is called the "duck type". 4. Things to note include the maintenance
